Stay alert and be prepared to take shelter if storms develop. .Excessive Rainfall...Flooding in urban areas, roads, small streams, and washes, particularly across the interior and north sections. There is a low chance of isolated flash floods. Elsewhere, plan for water ponding on roads and in poorly drained areas. .Excessive Heat...This level of heat affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration. Those extremely sensitive to heat face the highest risk. Some health systems and heat-sensitive industries could be affected. These conditions are most likely across the coastal and urban locations. .Marine Conditions...Hazardous conditions for small craft in areas with seas of 7 feet or higher, particularly across the Atlantic Waters. Small craft should exercise caution elsewhere across the local waters. .Rip Currents...Life-threatening rip currents are possible in the surf zone, particularly across the north-facing beaches. Isolated stronger rip currents may occur elsewhere, especially near piers, jetties, and channels. .DAYS TWO THROUGH SEVEN...Friday through Wednesday The heat risk will remain elevated through next week. Afternoon thunderstorms could lead to urban and small stream flooding each day along the Cordillera Central. A large, long period northerly swell will promote hazardous seas and life-threatening rip currents from late tonight through early next week. An unstable wet pattern will increase the chance for flooding rains and scattered thunderstorms early next week. .SPOTTER INFORMATION STATEMENT... Spotter activation is encouraged. Please relay any information about flooding, winds, waves, and rip currents to the National Weather Service in San Juan. $$ AMZ716-726-VIZ001-002-030900- St. Thomas St. John adjacent Islands-St Croix- Nearshore Atlantic and adjacent Caribbean Coastal Waters- 451 AM AST Thu Oct 2 2025 This Hazardous Weather Outlook is for portions of USVI. .DAY ONE...Today and Tonight .Excessive Heat...This level of heat affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration.
